ELECTRIC-LAMP RECEPTACLE AND PLUG.

Specification of Letters Patent.

- Patented July 20, 1915.

Application filed June 6, 1914. Serial No. 843,481.

To all whom'z't may concern Be it know nthat I, THOMAS AUSTIN Mon- Ius, a citizen of the United, States, residing at Lansford, in the county of Carbon and State of Pennsylvania, have invented new and useful Improvements in Electric-Lamp Receptacles and Plugs, of which the'following is a specification.

This invention relates to improvements in electric lamp receptacles or sockets and plugs. Y

In carrying out the present invention, it is my purpose to provide an electric lamp receptacle and plug which will be constructed in such manner that the plug carrying the lamp bulb may be readily inserted in and withdrawn from the receptacle without the use of screw threads thereby eliminating the necessity of threading the plug into and out of the receptacle or socket.

It is also my purpose to provide an electric lamp receptacle which will embody in its construction a shell of insulating ma terialcircular in cross section and having a closed end formed with an axial bore and an open end and a plate within the shell secured to' the closed end wall thereof and equipped with gripping fingers lying adjacent to the inner surface of the side wall of the shell at diametrically opposite points. and adapted to receive the plug end of the lamp, a contact being carried by the plate and insulated therefrom to engage the center contact on the end wall of the lamp plug.

lVith the above and other objects in view,

' the invention consists in the construction,

combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims. 4

In the accompanying drawings Figure 1 is a view in side elevation of an electric lamp receptacle constructed in accordance with the present invention, the 'globe being inserted in the receptacle and equipped with a plug formed in accordance with the invention. Fig. 2 is a longitudinal sectional view through the receptacle. Fig. 3 is a transverse sectional view therethrough. Fig. 4 is a view in side elevation of the lamp bulb and plug.

Referring now to the drawing in detail, 1 designates a shell preferably constructed of insulating material and circular in cross section and having a closed end 2 formed with'a longitudinal bore 3 alining axially with the shell and communicating with the .interior thereof and an open end 4. Disthereof is a plate 5, which, in the present instance, is in the form of an annular disk. Formed in the center of the plate 5 is an opening and secured within the opening and insulated from the wall thereof is a contact 6. Suitably fastened to the periphery of the disk at diametrically opposite points or formed integral therewith as desired are gripping fingers 7 lying adjacent to the inner wall of the shell and spaced apart and preferably having the confronting faces thereof concaved longitudinally as at 8. Connected with the contact 6 and the plate 5 respectively are the terminals of an electric current carrying cord 9 having the free terminals thereof suitably connected with a source of energy.

10 designates a lamp bulb of any suitable construction having one end thereofequipped with a plug 11, as usual. In ac cordance with the present invention, the side wall of the plug 11 tapers upwardly from the center thereof as at 12 and downwardly from the center as at 13 so that the plug may be readily slipped into the receptacle between the fingers 7 therein.

In practice, when it is desired to insert the lamp plug 11 within the receptacle, such plug is slid into the receptacle between the vfingers 7 and the concaved inner faces of the fingers grip the side wall of the.plug, incident to the latter conforming to the curvature of the fingers, the center contact on the upper end of the plug engaging the contact 6, while the side wall of the plug forms the electrical connection between the filament within the bulb and the fingers 7.

From the foregoing description taken in connection with the accompanying drawing,

the construction and manner of employing my invention will bereadily apparent. It

will be seen that I have provided an electric lamp receptacle and plug whereby the lamp may be secured within the receptacle without necessitating threading of the coengaging walls of the receptacle and plug and may be readily and whereby the lam rom he receptacle when quickly removed desired.

form of my invention by way precise details of construction herein described and dehneated, as modification and variation may be made Within the scope ofthe claims Without departing from the spirit of the invention.

I claim:

In combination, an electric lamp receptacle comprising a shell of insulating ma terial having a closed end and an open end, a plate within said shell secured to the closed end Wall thereof, gripping fingers carried by said plate and concaved longitudinally, a lamp plug adapted to fit hetween said fingers and having the side walls thereof conforming to the curvature of the 15 In testimony whereof I aflix my signature I in presence of two Witnesses.
